Intel has released betas of its software development tools for Mac OS X running on the Intel architecture. The tools consist of a Fortran and C++ compilers, a math kernel library and a performance primitives library. The tools are specifically designed to support Intel's Core Duo dual-core processor, as found in all the new Macs. The toolchain integrates into Apple's Xcode IDE, meaning the Intel compilers can be used in the production of Universal Binaries--applications packaged with code for both Power and Intel architecture machines.

One drawback of using the new tools may be that they don't support Objective C, which many Mac applications will be written in. Objective C is considered to be the native language for Mac OS X, and before version 1.5 there was little support for C++ in Xcode. Intel has no plans to support Objective C, so existing developers will almost certainly have to modify their applications to take advantage of Intel's dual-core processors.
